Indeed the EXB-10e (which may actually be a 10h according to some
release notes I read the other day) takes only about 80 seconds do to an
element initialize once it's already done one. However from its initial
state, either after power up, or after a bus reset, it seems to take at
least 120 seconds.
Obviously it isn't actually loading each tape as I feared it might.
Unfortunately I'm not normally anywhere within visual range of it, so
I've not actually watched what it does when it initializes.
